I bought the refillable cartridges for my Epson a few months ago. I found them wonderfully easy to use and the print quality was great. So when I ran out of black ink, these guys were my "go to" place. I can't tell you how much fun it is to walk into Staples (or wherever), look at the prices of ink cartridges (can you say "rip off"?) and just laugh. I'll be back!!
